Function setTypeNext

src/t_set.cpp:157–171

Move to the next entry in the set. Returns the object at the current * position. * * Since set elements can be internally be stored as SDS strings or * simple arrays of integers, setTypeNext returns the encoding of the * set object you are iterating, and will populate the appropriate pointer * (sdsele) or (llele) accordingly. * * Note that both the sdsele and llele pointers should be passe

 *
 * When there are no longer elements -1 is returned. */
